About this Hands-on Lab

In this hands-on lab, we will install software from source code on a CentOS7 system. Installing from the source code gives us an appreciation of using package managers such as dpkg and rpm, but it’s also good experience to be able to install from source if necessary.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Locate and Extract the Source File Archive
  1. The source file archive has been placed in the /home/cloud_user directory and must be extracted prior to use. Use the following command to extract the archived .tar file in /home/cloud_user :
    tar xzf htop-2.2.0.tar.gz

    This extracts the archive into the newly created folder htop-2.2.0 within /home/cloud_user.

Run the Configure Script to Prepare the Source for Installation
  1. Change to the htop source directory.
    cd htop-2.2.0
  2. Run the configuration script to prepare the source.
Compile the Source Code into Usable Binaries
  1. Compile the source code.

    This command will display output to the screen as it compiles the source code into binaries.

Install the Binaries
  1. Once the source code has compiled, run the following command to install the resulting binaries on the system:
    sudo make install
Run the `htop` Utility to Verify That Installation Was Successful
  1. When the binaries are installed, execute the htop command to verify that the installation was successful.
Remove the Installation
  1. Removing the installation is similar to installation. From the source directory /home/cloud_user/htop-2.2.0, execute the following command:
    sudo make uninstall

Additional Resources

A source code archive has been provided for you in the cloud_user home directory at /home/cloud_user.

Follow along with the video as we install the software from source, run the new utility it provides, and then remove the installation.

Note: Please wait about 2 minutes before starting the lab to make sure the lab has fully provisioned.

For first time Windows PuTTY users:

  • When you start PuTTY, you will see a dialog box.
  • In the ‘Host Name’ box, enter the public IP of the lab provided instance
  • From the ‘Connection type’ controls, select SSH
  • Once you have filled in the ‘Host Name’, ‘Connection type’, you are ready to connect. Press the ‘Open’ button at the bottom of the dialog box, and PuTTY will begin trying to connect you to the server.
